Designed for use with wall-hung toilets and back-to-wall toilets, concealed dual-flush cisterns let the user choose how much water to use when flushing the toilet. By using a lower volume of water to flush the toilet you can dramatically reduce your annual water consumption and contribute to the protection of this valuable natural resource.

How much water does a dual-flush toilet use?
The GROHE range of concealed cisterns allows you to choose between single flushing, start/stop flushing and dual flushing – this is determined by your choice of flush actuation plate. A dual-flush toilet offers a choice of two flush volumes: large, 6 liters and small, 3 liters. The cisterns can also be adjusted to flush with a reduced volume of 4.5 liters and 3 liters.

Flush plates for dual flush toilets
Choose a flush plate that complements the design of your bathroom faucets and shower for a fully coordinated look. GROHE flush actuation plates can be fixed either horizontally or vertically to work with your tiling scheme and also give access to the concealed cistern for maintenance.
